elections in half an hour here on bbc news. police in northern ireland have arrested two men in connection with the killing of lee—ra mckee in londonderry. the pair, aged 18 and 19, have been been detained under the terrorism act. the 29—year—old journalist — whose final moments were captured by cctv — was struck by a bullet as she was observing rioting in derry on thursday night. earlier i spoke to our reporter louise cullen, who told me more about these arrests. we know that these two teenage men were arrested in londonderry this morning. the police have said

they were brought from there to belfast to the psni serious crime suite for questioning. the footage showed lyra mckee‘s final moments and that video appears to show a gunman at leaning out from cover, firing a number of shots then running away and another man appears to gather a number of items from the ground before running away as well. lyra was standing with a number of otherjournalists beside a police 4x4 vehicle when she was struck by a bullet. the officer driving that police car actually drove through a burning barricade, we understand, to dry to get the young woman to hospital and help as quickly as possible. when she reached the hospital, lyra mckee died from her injuries. yesterday saw a huge outpouring of grief and shock and sorrow, notjust in northern ireland but around the world. even today, former president bill clinton has been tweeting his shock and sadness at the moor that

happened on thursday night. what about the range of political action and the sense there has been one message coming from all the communities in northern ireland to express their horror at this attack? the leaders of six of the parties attended a vigil in londonderry where lyra mckee was shot, leaders of the dup, the uup, the sdlp, sinn fein, the alliance party and the green party standing as one. they have released a joint statement earlier in the day saying the killing was a pointless and futile act to try to wreck the progress made in the past 20 years. yesterday was good friday, the good friday agreement was signed on good friday in 1998. there has been a universal condemnation from politicians here of the killing and many have attended other vigils. there will be more vigils across northern ireland today, perhaps indicative of the horror and revulsion that this young woman

plasma killing has provoked across the community. the group police are blaming for the murder are known as the new ira. let's find out more about them by speaking to henry mcdonald — he's a journalist based in belfast who has written several books about irish republicanism. good to speak to you again despite the circumstances. who are the new ira? they are an organisation formed in 2012, theirfirst ira? they are an organisation formed in 2012, their first communique was given to myself. they were formed out of the remnants of the real ira, that brought us the 0magh bomb atrocity and they also gather this new organisation, ex members of the provisional ira and formed into this new group, they morphed into this particular, the most lethal and dangerous of all, groups opposed to

the good friday agreement and the peace process. how big an organisation do you think they are? clearly not on the scale of the ira of old but still sufficiently dangerous to be a worry for the police. they are much smaller in terms of membership. 200 people maximum. they have a much, much reduced base of support used to hide weapons are help activists get across the border. it's a much reduced organisation but can be dangerous nonetheless. i was speaking last night to a security official who said one of the things worrying about this organisation is that they do have people who were experienced in the dark arts of bomb—making when they were in the provisional ira and some of those people have gone over to the new ira

in the last decade and have brought over bomb—making skills. there was bomb making equipment found on the border and it's booked some of the bomb disposal officers based in northern ireland who analysed it. it was a sophisticated and home—made. there is a capacity but because of them being small in nature and not having a massive base of support,, i think they are generally speaking being contained by m15 and it got a regional headquarters here. —— they have got a regional headquarters here. they will be able to spike their violence which they were going to do over the easter parade anyway because of the anniversary of the 1916 rising. they are dangerous but i don't think in the grand scheme of things despite the tragedy of this

week that they will destabilise the political peace process. they can't do it. the key thing you pointed to their as this is a group that doesn't have anything like the support and the wider republican community that the ira enjoyed at its height in the troubles. you've met some of these people, why do they remain convinced that violence will achieve their objective when it didn't for the ira for so many yea rs 7 didn't for the ira for so many years? is rather puzzling because the organisation is capable with a lot of technical know—how. the ira could not significantly shift british policy in terms of disengaging from northern ireland. how could this organisation do anything else like that? it's dubious but there are —— their‘s argument is that it's their duty to

do this, the good friday agreement does not deliver the promise of a united ireland, it gives the unionist population of northern ireland the veto over constitutional change, which is true, it does, nothing can change without a majority say so in northern ireland but it's almost like a nihilistic kind of reaction to the world moving on and it's interesting and significant that as well as the experienced hands have come over, hardliners, a lot of the recruits are very young, no different from lyra mckee, some of them were not even born when the ceasefire was declared or when the good friday agreement was achieved 21 years ago and they are part of a generation left behind and they are being used and manipulated and so on and recruited into these organisations so recruited into these organisations so you have that kind of combination of the left behind children of the

ceasefire in these older heads who are ideological eight stock in old—fashioned are ideological eight stock in old —fashioned republicanism of are ideological eight stock in old—fashioned republicanism of the early 20th century. you know dairy well —— derry. do you think the police will receive more cooperation now than they would have 20 years ago? do you think attitudes towards the police service have changed enoughin the police service have changed enough in public communities to make people willing to help with this investigation? there was never any cooperation. apart from anything else, there was a large number of informers within derry but the situation now, will they get information? probably because 20 yea rs information? probably because 20 years ago, all the parties did not support the police and they now do including sinn fein so they will get some support. however, there isn't a

section of youth in those hotspot areas of derry. i'm sure there will be more people willing... names were bandied about yesterday about the conmen and so forth, i don't know if they were true —— about the gun men. i'm sure they will receive information. thank you. police in london say they've now arrested more than 680 people since climate change protests began last monday. last night they removed a pink boat which had been blocking the road at oxford circus at the centre of the protests, saying they were trying their best to give nearby shops a chance to get back 0ur reporterjenny kumah

is at oxford circus. you've been there for the last couple of hours. it's obviously a glorious day. what about the protest, is it smaller than it has been during the week? been during the course of this week? the other man i was here yesterday and there was a considerable amount of people and it's building up here today and there was a big pink boat here as you say yesterday but that has moved on as well as the people glued to it. this morning, the police asked people to go to marble arch if they wanted to protest. at around half past ten they came to people here and said he will be arrested if you stay here but were almost two hours on from that and people are still here and the police presence is a little bit more diminished than it was earlier today. i went down to marble arch and there was a significant presence there. people have come from all of

there. people have come from all of the country, there are quite a few tense down there and at waterloo bridge as well there is a considerable presence, i understand. in terms of the powers that the police are using, they are using a section 1a order of the public notice act and that means they can ask people to move on and if they don't they can arrest them. the challenge has been that people have been willing to be arrested then when they have been released, they have been going back to protest and this has been putting pressure on police cells, the criminaljustice system. the latest figures are that 715 people have been arrested and 28 people have been charged. there was some concern yesterday about the situation at heathrow, there was a small presence there. today the police have said they have a robust plan in place to make sure that people can get away for the easter break and people can come into london to carry on about their business so the situation at the moment is, as i said, half past ten,

people who were told that there were going to be arrested, they did not wa nt to going to be arrested, they did not want to move to the official site at marble arch. briefly before i came on air there was a woman who basically said to people that if you don't move on to marble arch you will be arrested so if you want to move to marble arch, do that. that was one of the protest was telling people what the situation was. so far, it seems that a lot of people have decided to stay here for now. nearly 10% of heart attacks and strokes could be prevented in england and wales, if health checks were tailored to individual patients. at the moment, people over the age of a0 receive a heart check—up every five years. but new research from scientists at university college london, shows that high risk people should be screened more, and low risk patients much less. 0ur health correspondent james gallagher reports. somebody‘s risk of heart attack or stroke can be worked out by looking at risk factors, such as their blood pressure, cholesterol

levels or family history. doctors use the information to give advice on lifestyle changes, or to prescribe drugs like statins for cholesterol or blood pressure. the study in the lancet followed 7,000 people to see how their risk changed over time, then investigated whether there was a better way of performing routine checkups. currently, people should be seen every five years, but the study suggested the healthiest people could be seen every seven years, the less healthy every year. the team predicted 8% of heart attacks and strokes will be prevented with tailored testing. that works out at about 5,000 fewer heart attacks and strokes every year in england and wales. researchers say these personalised checks would not cost the nhs any more money. the british heart foundation says it could potentially save lives but warned it could be hard to implement and that too few people were having current assessments. a scheme to help people with mental health illnesses find a job —

if they want one — is being expanded. england is rolling it out the individual placement and support scheme to 28 new areas. employment specialists will offer coaching and advice, along with practical tips on preparing for interviews. it's hoped that within five years, it will help 55,000 people per year. i'm joined now by brian dow, deputy chief executive of the charity, rethink mental illness. thank you for being with us. we are probably familiar with the stats of the number of people who at some point in their life have some mental illness to deal with and it's a reminder for lots illness to deal with and it's a reminderfor lots of illness to deal with and it's a reminder for lots of people in our workplaces, in and around us, who have in the past or will do in the future, you're talking about people who have effectively not been in the workplace or at work and are trying to keep it that way. traditionally if you had a severe mental illness,

you tend to experience a long wait for treatment and testing go to get a diagnosis and ultimately the wrong kind of medication. that meant that frankly your illness had developed so frankly your illness had developed so much that you are unlikely to get into employment and the prospect of that was deeply frightening. hopefully with the kind of improvements and investments gone into the mental health system recently, all of that should happen quickly so that's the basics. in fa ct, quickly so that's the basics. in fact, the research shows that two thirds of people even who have a severe mental illness will actually wa nt to severe mental illness will actually want to work but have not really been given the right support to get into work and once they are in that employment, to stay on that. and that, i suppose, employment, to stay on that. and that, isuppose, is employment, to stay on that. and that, i suppose, is the other element, you're notjust helping the patient, the client, but you are having to work with employers to help them see beyond the illness.

exactly, people with a mental health problem are no different from anybody else. you want a job because you want security and want to be socially connected and a job brings in income so you have money to spend and don't feel impoverished and the isolation that comes with that. helping both the person into thejob but also supporting the employer to understand what it's like to live with the mental health condition, often one that may fluctuate so that the symptoms are not obvious to see, is good for both individual, the employer and the economy as a whole so employer and the economy as a whole so it's really fantastic news. we should stress this is a voluntary scheme, there is no question of people being forced onto this and it's nothing to do with benefits, it's nothing to do with benefits, it's purely about people who believe they would like to work and find out if it is practical for them and what kind of support may be available for them. yes and that's an important point to make because although about

two thirds of people with a severe and enduring mental illness want to work, there is probably around about a third of people who really count on are not able to hold down full—time permanent work. those people still might want to be able to volunteer or do something valuable so as long as there is support for people and understanding and the benefit system itself is giving the right kind of support to people, in time, they can have some sort of gradual return back to work so sort of gradual return back to work soi sort of gradual return back to work so i think that distinction is an important one to make. what about confidence of clients you've worked with? what impact has worked hard on the people you've dealt with? in terms of the things you are talking about like social isolation and confidence, particularly in recovery from mental illness. it's important to remember that if you have a mental health condition, once you have the basics in place, the things that will move your health up and

down are things like social connectedness, work, decent housing isa connectedness, work, decent housing is a really important factor, so the difference it makes being in work, being part of the network, having friends you can connect with is enormous in terms of people's confidence, of course, but as you indicate, the long—term recovery. this is being expanded in 28 new areas, you've got to find the people who can provide the expertise and the knowledge. coming from the charity sector, how difficult is that going to be? i think it will be a challenge. the single biggest difficulty i think in delivering better and mental —— better mental health care has been the availability of a well—trained workforce. it's increasingly becoming an attractive career to move into because people recognise that actually there are so many of us that actually there are so many of

us with a mental health problem and being able to do something that is just transforming some of the's health but perhaps transforming their entire life hopefully makes it their entire life hopefully makes it the kind of career that people want to come into. i certainly hope so. and if they are interested, what are the pass into it? yellow —— and if they are interested, what are the pass into it? yellow -- nhs england are looking at a number of preferred employers who will no doubt set up a recruitment programme andi doubt set up a recruitment programme and i really hope people will get involved because it's an opportunity to transform lives. a british man hailed as a hero for stopping a global cyber—attack has made a public apology after pleading guilty to malware charges in the us. 24—year—old marcus hutchins was credited with stopping an attack which threatened the nhs and other major organisations two years ago — but yesterday pleaded guilty to charges relating to a banking malware that could be used to steal passwords in 2014. he has since released a statement

on his website, saying... "i regret these actions and accept full responsibility for my mistakes. having grown up, i've since been using the same skills that i misused several years ago for constructive purposes." two people have been arrested after a six—year—old boy was shot and injured in wolverhampton. police say a group of men opened fire on a house in the eastfield area of the city in what they have described as a "hugely reckless act". the boy's injuries are not thought to be life threatening. the headlines on bbc news: two people have been arrested over the murder of lyra mckee in londonderry. the teenagers are being held under the terrorism act. police in london say they've now arrested more than 700 people since climate change protests began last monday. researchers say nearly one in ten heart attacks and strokes could be prevented if routine check—ups were better targeted. the easter weekend is off to a scorching start,

with temperatures expected to reach 26 degrees over the bank holiday, making parts of the uk hotter than the mediterranean. let's cross to our correspondent helena lee, who's in hyde park this is definitely a case of drawing the short straw for the reporter who gets sent out to cover the weather! you've got to find hats, sun block and the neediest ice cream —— nearest ice cream! i'm very envious, helena. this is the serpentine in hyde park in central london. you can see the water glistening and people out on pedal boats, it is really

glorious and it does feel very hot indeedin glorious and it does feel very hot indeed in the sunshine and those temperatures have been creeping up. it's going to be warmer than it was yesterday. we've had a look at the temperature here in hyde park and its reach 20 celsius —— it has reached 20 celsius. temperatures are expected to rise. in terms of records, this is going to be the hottest day of the year so far. 0ne of the hottest easter weekend is on record. the actual record was in 1949 record. the actual record was in 19119 when the temperature reached 1949 when the temperature reached 29.4 celsius in camden square in central london. it's not going to quite reach that here today or across the country but temperatures are expected at about 25 celsius, even 26 celsius in some parts and you may want to think about some of those people who are headed off to the mediterranean, particularly

spain, tomorrow but be slightly lower tomorrow but for the next four days or so, it should be warm and then the middle of next week, that is when we can expect some showers but you are more than welcome to come down here later if you want! i think! may welcome to come down here later if you want! i think i may take you up on that kind offer! enjoy the sun. house plants do much more than simply decorate our homes — they can bring a sense of calm and help the environment. currently, plants which aren't considered food, are subject to full vat, but campaigners say that should be reduced. laura foster has more. becca had struggled with anxiety and depression for months. counselling didn't work,

medication didn't work,
